It will also present an opportunity for them to interact with influencers who can contribute to the marketing and distribution of their products, thus boosting their value.Creators and those who wish to become creators can upload the products they make on doDRESS. When a product is sold, every individual in the platform’s Web3 ecosystem who contributed to making it will receive a portion of the revenue.Visitors, on the other hand, can customize their own clothing by printing designs created by the artists themselves through doDRESS’s fashion stickering service, which is available both online and offline at the pop-up store. The platform also said that it would give out custom doDRESS products worth KRW 40,000 (approximately $30) on a first-come, first-served basis to 70 visitors on weekdays and 200 on weekends.Future plans for growthIn the future, doDRESS aims to expand on a global scale and add more clothing products to its services utilizing various production techniques like 3D printing.The pop-up store will be open until next Wednesday (local time) in Seongsu-dong.

Busan BDX Consortium named preferred bidder for Digital Asset ExchangeIn the latest development of Busan’s initiatives in the blockchain industry, the Busan BDX Consortium has been named the preferred bidder for the project aimed at setting up and operating the Busan Digital Asset Exchange (BDX).The South Korean port city of Busan organized a bidding competition for the project, whose application deadline was Nov. 28. This competition saw participation from two companies. Following this, a project proposal evaluation committee was recently assembled to review the presentations of these bidders at the Busan International Finance Center (BIFC).The selection of the Busan BDX Consortium as the preferred bidder was made after an evaluation process where 90% of the assessment criteria were qualitative and the remaining 10% were based on quantitative factors. The consortium is led by Itcen, a Seoul-based tech company that specializes in digital transformation.Photo by Pang Yuhao on UnsplashNegotiations and future stepsBusan City will now promptly enter into negotiations with the consortium, with the goal of finalizing its decision before the end of this year. Following the selection, Busan intends to sign a business agreement with the chosen bidder in January to move forward with the project.BDX is a platform designed to use blockchain technology for the digitization and trading of assets linked to Busan’s infrastructure in logistics, culture and finance. It is planned to be a fully private entity, a decision aimed at fostering freedom and creativity in its operations. Meanwhile, the city will offer administrative and financial support in accordance with its local ordinances.Son Seong-eun, who leads the Finance and Start-up Policy Bureau of Busan City, remarked that the development of BDX is set to establish a solid foundation for the blockchain industry and enhance the region’s economic growth. Aiming to establish Busan as a leading global blockchain hub, the city is committed to providing ongoing support for the new digital exchange, Son added.Blockchain to encourage volunteeringBesides the BDX project, Busan is also leading another blockchain initiative. Starting next year, the city will test a blockchain-based platform designed to manage and track volunteer experience points for its residents.The platform being developed by Busan will facilitate the connection between individuals seeking volunteer assistance and those who participate in volunteer activities. Its goal is to foster a virtuous cycle that contributes positively to society, enhancing the efficiency and impact of volunteer efforts within the community.Citizens will be able to accumulate points on the blockchain platform by participating in socially beneficial activities like distributing staple goods and contributing to carbon emission reduction. These points can then be redeemed for various benefits like attending concerts or accessing public parking lots. This endeavor to encourage volunteering is set for a full-scale launch in 2025.

Singapore’s UniPass Plays Role in ERC-4337 Vulnerability FixSmart contract wallet provider UniPass and crypto infrastructure firm Fireblocks have successfully addressed a significant vulnerability in the Ethereum ecosystem.Photo by Nenad Novaković on UnsplashAccount abstraction vulnerabilityThis vulnerability, identified as the ERC-4337 account abstraction vulnerability, posed a critical security risk to hundreds of mainnet wallets. The joint effort between Fireblocks and UniPass was detailed in a blog post published to the Fireblocks website on Thursday.This vulnerability, if exploited, could have enabled a malicious actor to execute a complete takeover of the UniPass Wallet by manipulating Ethereum’s account abstraction process. The vulnerability represented a substantial threat to the security of smart contract wallets, as it could lead to unauthorized access and fund drainage.Improving user experienceAccount abstraction, as dealt with via ERC-4337, is a mechanism that introduces a novel way of processing transactions and interacting with smart contracts on the Ethereum blockchain. It allows for a more flexible and efficient handling of transactions, transcending the traditional distinction between externally owned accounts (EOAs) and contract accounts.EOAs are controlled by private keys and can initiate transactions, while contract accounts are governed by the code of a smart contract. When an EOA initiates a transaction with a contract account, it triggers the execution of the contract’s code. Account abstraction introduces the notion of abstracted accounts, which are not tied to a specific private key and can initiate transactions and interact with smart contracts, similar to EOAs.In the context of ERC-4337, an account executing an action relies on the EntryPoint contract to ensure that only signed transactions are executed. Typically, these accounts trust a single audited EntryPoint contract to validate user operations before executing commands. However, the vulnerability resided in the fact that a malicious or buggy EntryPoint contract could potentially skip the validation step and directly call the execution function, bypassing essential security measures.This vulnerability, identified by the two firms, had allowed attackers to seize control of UniPass wallets by replacing the trusted EntryPoint of the wallet. Once this takeover was completed, the attacker could access the wallet and drain its funds.It’s worth noting that the vulnerability posed a threat to several hundred users who had activated the ERC-4337 module in their wallets, making them susceptible to exploitation by any actor on the blockchain. Fortunately, the wallets affected by this vulnerability contained only small amounts of funds, and swift mitigation efforts were successful in preventing further harm.Company mergerEarlier this year, Singapore’s UniPass merged with Chinese wallet provider Keystone to form Account Labs, a company which has been incorporated in Singapore. At the time, Keystone founder Liu Lixin outlined that further developing account abstraction-derived products was the objective of the creation of Account Labs. He stated:“We are on the cusp of a Web3 Account Abstraction revolution. Together, we’ll drive rapid transformation, making the transition from Web2 to Web3 effortless for users. Our goal is to ensure everyone can securely and smoothly manage a decentralized account. We welcome partners to join us in advancing the Web3 account domain.”In furthering that objective, Account Labs announced on Thursday that it had raised $7.7 million in a funding round led by Amber Group, MixMarvel DAO Ventures, and Qiming Ventures.
